"In an effort to help consumers find safer products, the Environmental Working Group has created the first online guide that rates more than 2,000 household cleaners with grades A through F for safety of ingredients and disclosure of contents," according to a statement from the group.

Some brand names received a passing and failing grade because of different variations in their product.

We've listed the top 10 highest- and lowest-ranked items of household cleaners in 10 categories, which include: air fresheners all purpose, bathroom, dishwashing, floor care, furniture, kitchen, laundry cleaner and other cleaners, as provided by the group.
